Sure, but the OP's original note explicitly said he had a dict and
asked how to test if it was empty. He was used to seeing/using "not
mydict", but had recently encountered "mydict == {}". Given those
preconditions, the correct answer is that "not mydict" is the way to
go (idiomatic Python). Using "mydict == {}" is clearly suboptimal.
